Hi people, i'm running the project that comes with the book of jbpm development guide, the chapter 8.
I run everything, i have configured jbpm 5.4 with jboss 7.1.1 and oracle like my db persistence.
but when i want runit appear the next exception. Any idea why??

The code where appear the exception is the next.

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
        kbuilder.add(new ClassPathResource("process-async-interactions.bpmn"), ResourceType.BPMN2);
        if (kbuilder.hasErrors()) {
            for (KnowledgeBuilderError error : kbuilder.getErrors()) {
                System.out.println(">>> Error:" + error.getMessage());
            }
            System.out.println(">>> Hay problemas con el archivo .bpmn! ");
        }
        KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
        kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
        Environment env = EnvironmentFactory.newEnvironment();
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.runtime");
        env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
        env.set(EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager());
        // Let's create a Persistence Knowledge Session
        System.out.println(" >>> Let's create a Persistent Knowledge Session");
StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env); //here generate the exception.



The exception code....

Exception in thread "main" java.lang.NoSuchMethodError: org.drools.SessionConfiguration.addDefaultProperties(Ljava/util/Properties;)V
